Not at all obvious if the process by which we make that choice is also dependent on our nature/nurture. It may reach a different conclusion than the sub conscious but is not necessarily any more free. Isn't that point obvious?
No, it isn't. The conscious mind is able to either obey its nature/nurture tendency or do otherwise. Always! You are never obliged to make a certain choice ... you can always do otherwise.
This discussion always founders because of the terminology. You use
nature to mean your typical characteristics, and nobody would argue that we cannot act out of character sometimes, maybe just for the hell of it. We have enough degrees of freedom to be able to act out of character on occasion, but does that equate to being able to defy the law of cause and effect ? does that mean that humans, uniquely, can operate outwith the laws of nature ? That is a much more profound consideration and it is a view from the theist stable that humans are different, have free agency. I am an atheist however, so I accept that humans are actually just creatures at the end of the day, and like all creatures of flesh and blood, we must be constrained by the overwhelmingly deterministic laws that govern flesh and blood. A belief in free-will is ultimately a belief in the supernatural.
